Also been curious to control hardware/softwareand would love to find a way to play synthesizers with guitar so looked this up.
Read one review and it seems that it does not allow for bending etc when playing synthesizers and do not know how well it works with the app plus weird strings.
SO maybe this post is a little bit redundant but in either case putting it out as it could be worthwhile to test it out if possible and having the monies.
There is some similar news that should be posted that is more interesting if you like to make synthesizer sounds with guitar and do not care about the midi part... (tomorrow?)
With the neatly designed Jammy Guitar mobile app, you will mix practice and pleasure in the most fun and effortless way.
Shape your unique sound by choosing your guitar type and applying FX pedals to it. Explore a variety of guitar tunings available at a single tap.
Train your sense of rhythm playing to an easily adjustable metronome. Jam along to 20 live recorded full-band backing tracks — it's like having a whole band in your phone!
Don't know how to jam? No worries! Each backtrack is accompanied by a set of appropriate notes that you can combine into solos so even a beginner will be able to drop some cool licks! The best thing is that you can use most of those features with your ordinary guitar as well as with Jammy.
